Design, synthesis, docking study and biological evaluation of some novel tetrahydrochromeno [3?,4?:5,6]pyrano[2,3-b]quinolin-6(7H)-one derivatives against acetyl- and butyrylcholinesterase

Novel hybrid derivatives of two known scaffolds; tetrahydroaminoquinoline and coumarin were synthesized and evaluated for both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities. By means of an efficient nanocatalyst, the reaction time for the syntheses of the target compounds was reduced. Subsequently, Ellman’s modified method was used to evaluate the enzyme inhibitory activity of the synthesized structures. It was observed that most hybrid structures were moderate to potent inhibitors of AChE compared to Tacrine as the reference drug among which 7f with 4-fluorophenyl substituent was the most active compound (IC50 = 5 nM).

Polymeric pH indicators immobilized PVA membranes for optical sensors of high basicity based on a kinetic process

Two kinds of polymeric pH indicators PPF (phenolphthalein-formaldehyde product) and CPF (o-cresolphthalein-formaldehyde product) immobilized cross-linked poly(vinyl alcohol) membranes (PPF-PVA and CPF-PVA) for optical intermittent determination of high basicity ([OH-] = 1-8 M) based on a kinetic process were developed. In our previous work, we had demonstrated that PPF-PVA and CPF-PVA could perform the determination of high pH values from pH 10.0 to 14.0. Here the discoloring kinetic behaviors of PPF-PVA and CPF-PVA were compared with those of free phenolphthalein, o-cresolphthalein and thymolphthalein. Experimental results and theoretical analysis indicated that the response behaviors of the optodes’ membranes in concentrated NaOH solutions were diffusion-independent and still complied with the pseudo-first-order kinetics. In addition, two data analysis methods for determination were presented. One was directly based on the reduced absorbance; the other was based on the discoloring kinetic constant. It was found that the latter could perform a rapid (60 s) and reliable (relative standard deviation: 2.6%) determination for high basicity. These kinds of optodes can be used repeatedly when they are immersed in low-pH solutions to regain the protonated form after each determination.

Recent trends in microencapsulation for smart and active innovative textile products

The industrial interest for microencapsulation techniques to produce innovative materials has increased in the last years. Microencapsulation shows several advantages for textile industries since active compounds, such as vitamins, essential oils, antimicrobials and/or antibiotics can be isolated to protect them from environment factors (oxygen, light, moisture and temperature). Microcapsules are also used for the controlled release of fragrances or even heat, to mask undesired properties of the active components and to convert liquid substances into solids with increased compatibility. In this review, the application of microencapsulation techniques to obtain innovative materials for the textile sector has been highlighted. The main known techniques have been briefly described, including interfacial, suspension and in situ polymerizations as well as spray drying, complex coac-ervation, centrifugal extrusion processes, fluidized-bed-coating and sol-gel techniques. Different mechanisms have been also described based on the different properties offered by permeable or non-permeable capsules. Finally, the development and application of microencapsulation in smart (phase change materials, photochromic, thermochromic and flame retardant microcapsules) and active textiles, including antimicrobials and the use of different additives with pharmaceutical and/or medical properties, insect-repellent systems and fragrant solid carrier materials have been briefly discussed.

Synthesis of imidazopyridine-fused indoles via one-pot sequential Knoevenagel condensation and cross dehydrogenative coupling

A simple and efficient strategy for the synthesis of imidazopyridine-fused indoles has been developed that involves one-pot sequential Knoevenagel condensation of readily available active methylene azoles with N-substituted-1H-indole-3-carboxaldehydes or N-substituted-1H-indole-2-carboxaldehydes followed by palladium-catalyzed intramolecular cross dehydrogenative coupling reaction. A series of 36 derivatives was prepared by using this strategy. The products were obtained in moderate to excellent (32-94%) yields and showed broad substrate scope with tolerance of various functional groups and was amiable for gram scale preparation without problems.
